When going to bid for that special Item that you have been looking for, you need to make sure you read ALL of the ad and not be swayed by the picture alone.
Occasionally, unscrupulous sellers will have stolen their picture or used a stock photo and hide their postage within the auction ad.
If the postage is not clearly shown in the P+P box, then look through the description(more than once) and if it isn't clearly shown then you need to steer clear and look elsewhere.
